Over recent years the marine reserve had received increasingly more recognition, including from aquatic legend Jacques Cousteau, who had said it was one of the word's top 10 diving spots.
"The island's underwater cliffs drop steeply through crystal waters to form a maze of archways, caves and tunnels adorned with sponges and a vivid array of underwater vegetation," said Lonely Planet.

One of the unique features of the Poor Knights was the entirely protected environment, Mr Jongejans said.
"It's building on the sustainable use of the environment," he said. "It's only going to go from strength to strength."
Also listed were: Raglan surfing, Auckland sailing, blackwater rafting in Waitomo, Tongariro River rafting, kayaking in Okarito Lagoon and Abel Tasman National Park, Torrent River canyoning, swimming with seals in Kaikoura and swimming with dolphins in Akaroa.
